There is no test that is officially-recognized to “prove” someone has ME or CFS. However, some doctors and patients find the tests on this page to be helpful. Please keep in mind that many people are not diagnosed based on testing. Many people are diagnosed based on symptoms and ruling out other conditions.

Tilt Table Tests
A tilt table test is a test used to document changes in blood pressure and heart rate for patients with Myalgic Encephalomyelitis and Chronic Fatigue Syndrome. Some readers report that beta blockers or other medications can interfere with the test results. Here’s how Iris Took a Tilt Table Test
Some people who cannot get a tilt table test, instead try the NASA Lean Test (a “poor man’s tilt table test”). It does not require special equipment and any doctor can do it if they are willing. Some people have had success printing out the form and instructions, bringing it to their doctor, and requesting a special appointment to perform the test.

The CPET test is often used by people applying for disability through their employer’s insurance. Here’s How Dahlia Used a CPET to win disability through her employer. And here’s How Iris Got a CPET. Lavender figured out a way to get many of the benefits of a CPET without all of the drawbacks: Lavender Solves the Problem of the CPET
There are several different types of brain scans people have found helpful in documenting ME and related conditions: SPECT and xenon SPECT scans of the brain, MRI scans of the brain, PET scans of the brain and EEG/QEEG brain maps. The Hummingbird Foundation Testing for ME explains each of these tests. You can read the short explanations or the long explanations.
There is no specific blood test that is universally recognized as accurately measuring CFS or ME. However, the links at the bottom of this page include blood tests and other types of medical tests that some patients and doctors have found helpful. EBV blood work is a common one.
Tests from the Social Security Ruling
The Social Security Ruling for Chronic Fatigue Syndrome includes a list of tests that can be helpful for applying for disability. These include some of the tests mentioned on this page, as well as sleep studies, EBV bloodwork, exercise stress tests, and several other tests.
In addition, the ruling recognizes “any other laboratory findings consistent with medically-accepted clinical practice.” So, any of the other tests on this page also has the potential to be helpful. This ruling is for disability applications in the US. Most other references on this page are international.
If you have problems with balance or disequilibrium, a The Romberg Test is a small, simple test your doctor can do in her office anytime. It may not give you a great deal of information, but if you are looking for more documentation on your condition, you can ask your doctor to do a Romberg test and to note the results in your records.
